Bell-202/202T Modems

DC Powered Bell 202 / 202T And V.23 Modems

Modems : ASE’s DM series products are Bell-202/202T and V.23 modems designed for operation over leased line communication circuits as commonly used in the electrical power and pipeline SCADA industries. These modems have been designed with many commonly requested features including 900Hz soft-carrier turnoff, LED indicators, digital control over most timing parameters (in 1 millisecond increments), transmit levels from 0 to -31db, a PTT (Push to Talk) circuit, and input power from 5 to 160 VDC. The primary modem circuitry is based on commercially available ICs with many years of field proven operation. All Bell modems are available in a 19″ rack configuration with a 16-slot custom backplane, or packaged in a metal box. For IED/RTU manufacturers, a low-cost “board only” version can mount directly in the Remote unit. Power, Timing, Levels, Isolation, LEDs, Other, Packaging, Testing your modem, Modem Part Numbers
